I think it's unlikely that we'll be able to get the necessary people to play straight up covers the way they are done in CREID. However, it would definitely be fun to put together an eclectic celtic band to play arrangements of Xeno and Chrono tunes. I would especially love to play live arrangements of Omen, My Village is Number One, and Bonds of Sea and Fire.
By the way, the pipes used in CREID aren't bagpipes; they're uilleann pipes.
Anyway, count me in for whistles (I have two whistles, one high D and one low D. They can play most easily in D and G) and/or guitars.
